GMM220 Carbon Dioxide Modules for
Demanding OEM Applications
For Harsh Environments
The Vaisala CARBOCAP
®
Carbon
Dioxide Module Series GMM220 are
designed for Original Equipment
Manufacturers (OEM’s) requiring
carbon dioxide measurements in
harsh and demanding applications.
Vaisala CARBOCAP®
The GMM220 series modules
incorporate the industrial Vaisala
CARBOCAP
®
Sensor. The patented
sensor has unique reference
measurement capabilities. Its critical
parts are made of silicon; this gives
the sensor outstanding stability over
both time and temperature.
Since water vapor, dust, and
most chemicals do not affect the
measurement, the GMM220 series
modules can be used in harsh and
humid environments.
The Vaisala CARBOCAP
®
Carbon Dioxide Module Series GMM220 withstand
harsh conditions. They provide high carbon dioxide measurement accuracy
over wide temperature and relative humidity ranges.
Interchangeable Probes
The GMP220 probes are
interchangeable. They can be
removed, reattached or replaced at
any time – without the need for
calibration and adjustment. The
interchangeable probes make
calibration and eld service easy. In
addition, the measurement range can
be changed simply by replacing one
probe with another.
Di erent Confi gurations
The user has a choice of
measurement ranges up to 20 % CO

:
the Vaisala CARBOCAP
®
Carbon
Dioxide Module GMM221 for higher
and the Vaisala CARBOCAP
®
Carbon
Dioxide Module GMM222 for lower
concentrations of CO

.
Different power supply voltages,
output options, as well as cable
lengths, connectors, and mounting
gear are also available.
